3D Memory Game is a game in which you play with four tile pairs, making eight pieces. In each round, one piece is shown and you have to find the matching piece. To make things complicated, two pieces are exchanged after each round.

SGX Engine Core contains the basic functionality which underpins SGX,
a 3D graphics engine from Steven Goodwin. It is based around a series of
null drivers and loosely-coupled modules to facilitate an infinitely
upgradable engine. It is primarily suited to games and digital TV
backdrops.

Solid|matter is a 3D CAD application for product design. It is planned to feature parametrical, solid-based modeling, a sketcher with associative dimensions, and basic simulation of assembly kinematics. It is also designed to integrate well with the Gnome desktop.

DungeonHack is an engine for role-playing games (RPG) that are non-linear with large scale environments. Its goals emphasize procedural generation, modern 3D graphics, and dynamic, interesting worlds and characters. Currently, there is specific focus on one such world.

YafaRay is a raytracing engine. Raytracing is an image rendering technique for generating realistic images by tracing the path of light through a 3D scene. A render engine consists of a "faceless" computer program that interacts with a host 3D application to provide specific raytracing capabilities "on demand". Blender 3D is the host application of YafaRay.

The Cafu Engine is an all-purpose, modern 3D graphics engine and game development kit. It is feature complete to get you started quickly. It can be used to create a variety of 3D applications, including games, simulations, and training and architectural software. Written in C++, the tools, libraries, and framework have been designed to make the development of new games and other 3D applications easy. They are actively and continuously developed in order to provide the latest technology.

Penumbra is a first person horror adventure focusing on story, immersion, and puzzle solving. Violence and combat are hardly an option: the player has to use wits to guide Philip through his final test, which makes the series unique in offering a truly dangerous and terrifying experience. Played from a first person perspective and powered by a 3D engine utilizing cutting edge technology, Penumbra is a true advancement to the adventure genre. The unique physics system allows for true environmental interaction: The player can open drawers, pull levers, pick up objects and manipulate those objects in 3D space, all using natural mouse movements. This creates a highly interactive and immersive game world.
